while PR #2357 [1] was being implemented the question came up:
would be better to change the PING resource from CSS to an image so that
some terminal based browser may still able to pass the test [1]
This patch implements a POC in where a <img src=token> tag is loaded instaed a
CSS.
To test this patch activate limiter and link_token method [3] and start a
developer instance::
make run
In your terminal browser open http://127.0.0.1:8888/search?q=foo
If the browser is suitable for the link_token method, it loads the image and the
following messages appear::
DEBUG searx.botdetection.limiter : OK 127.0.0.1/32: /clientft61aak7fzyu6o6v.svg ...
DEBUG searx.botdetection.link_token : token is valid --> True
DEBUG searx.botdetection.link_token : store ping_key for (client) network 127.0.0.1/32 (IP 127.0.0.1) -> SearXNG_limiter.ping[...]
Browsers that do not load images will be blocked: If you try by example::
lynx http://127.0.0.1:8888/search?q=foo
you will see a WARNING message like::
WARNING searx.botdetection.link_token : missing ping (IP: 127.0.0.1/32) / request: SearXNG_limiter.ping[...]
Modern terminal WEB browser do support `<img>` tag as well as CSS:
browsh http://127.0.0.1:8888/search?q=foo
